Induction of labor in women with low Bishop scores (June
2016)

Previously, the HYPITAT randomized trial demonstrated that
routine induction of labor in women with mild preeclampsia
or gestational hypertension at >360/7weeks resulted
in lower rates of adverse maternal outcome and cesarean
delivery compared with expectant management withmaternal/fetalmonitoring.
However, the outcome of women with unfavorable cervixes was
not analyzed separately.

In a secondary analysis of data from this trial and DIGITAT
(pregnancies complicated by fetal growth restriction),
induction of labor at term in women with a median Bishop
score of 3 (range 1 to 6) was not associated with a higher
rate of cesarean delivery than expectant management, and
approximately 85 percent of women in both groups achieved a
vaginal delivery [1].
Thus, an unfavorable cervix does not alter the decision to
induce labor in women with pregnancy-induced hypertension at
term. (See"Preeclampsia: Management and prognosis", section on
'Preeclampsia without features of severe disease'.)
